A properly installed and well-maintained roofing system can last for decades. However, there will come a time when your asphalt shingle roof, metal roof or other roofing membrane will experience deterioration. So, how do you know if your roof is failing due to normal aging or weather-related damage? 

Deterioration Due to Normal Aging

One of the most obvious signs of an aging roof is fading color. Asphalt shingles, in particular, will start to lose some of their vibrant color over time due to prolonged exposure to sunlight. Harmful ultraviolet (UV) rays not only cause the premature aging of your roof, but also heat up the attic, resulting in a warmer home. While faded shingles do not necessarily warrant professional attention, it is still a must to keep a close eye on them for it is likely that they are nearing the end of their service life.

Naturally, sun exposure will cause your roof to lose its flexibility, causing it to lose some of its mineral granules as it ages. This is not a bad sign as asphalt shingles should undergo fairly gradual and even-spread granule loss throughout its lifetime. 

Deterioration Due to Roof Damage

Any exterior services provider will attest that loose flashing around the trim, chimneys, valleys and skylights of your home is often a cause for concern. If the flashing lifts due to contractions and expansions, it can allow rainwater or moisture to leak into the living space. Cracked vents, which are normally caused by the frequent cycles of hot and cold temperatures, on the roof should also be repaired before leaks occur. 

Another common symptom of a damaged roof is the presence of sagging. In addition to the excessive weight of structures, layers of snow and ice can force the roofing system to droop in between rafters or trusses.
